With a snarl of pain and rage the beast leaped at her. Its broken leg caused it to fall short by several yards, and the pain of the injured limb, when it landed, caused the catamount to howl again and tear up the snow in its agony.

Ruth could not run; she was rooted to the spot. She had bravely shot at the creature once. Better had it been for her had she not used the rifle at all. She had only turned the wrath of the savage cat from Reno to herself.

And Ruth realized that she was now its helpless quarry. She could neither fight nor run. She sank back into the snow and awaited the next leap of the panther.

At this very moment of despair—when death seemed inevitable—there was a crash in the bushes behind her and a figure broke through and flung itself past her. A high, shrill, excited voice cried:

"Give me that gun! Is it loaded?"

Ruth could not speak, but the questioner saw instantly that there were cartridges in the magazine of Tom Cameron's gun. He leaped upright and faced the crouching cat.

The panther, with a fearful snarl, had to change the direction of its leap. It sprang into the air, all four paws spread and its terrible claws unsheathed. But its breast was displayed, too, to the new victim of its rage.

Bang!

The rifle spat a yard of fire, which almost scorched the creature's breast. The impact of the bullet really drove the cat backward—or else the agony of its death throes turned the heavy body from its victim. It threw a back somersault and landed again in the snow, tearing it up for yards around, the crimson tide from its wounds spattering everything thereabout.

"Oh, it's dead!" cried Ruth, with clasped hands, when suddenly the beast's limbs stiffened. "You've killed it!"
